RAZOR-STROPPING DEVICE.

Specification of Letters Patent.

Patented June 21, 1910.

To all whom it may concern:

Be it known that I, CHARLES FREDERICK BENEDICT, a citizen of the UnitedStates, and a resident of the borough of Brooklyn, in the county ofKings and State of New York, have invented certain new and usefulImprovements in a Razor-Stropping Device, of which the following is aspecification.

This invention relates to a razor stropping device. Its organizationcomprises essentially a frame or holder in which are formed guides for ablade carriage, and a presser plate located over the carriage whichsecures a strop in frictional engagement therewith. The strop on eachside of the carriage is guided over guide rollers in the frame, so thatby alternately pulling the ends of the strop the carriage is translatedand reciprocated from one side to the other of the said frame or holder.

This invention is an improvement of the application for a razorstropping device filed July 17, 1907, Serial Number 384,153, and differsfrom said application essentially in the construction of the bladecarriage with its means for securing a blade therein, and theconstruction of the guide rollers of the frame or holder.

With the carriage of the present invention are formed jaws that can holdan ordinary razor blade, or a supplemental blade holder for securing theblade of what is known as a safety razor, A strop adjuster is connectedwith the frame, so that when the carriage is translated and reciprocatedby alternately pulling the ends of the strop, the leg of the strop thatis adjacent to the blade is pushed from and clear of the same, beforethe blade is moved. The friction of the strop between the blade carriageand the presser plate translates and reciprocates the carriage, whichcauses the opposite sides of the blade to alternately come in the pathof the opposite legs of the strop. The relation of the parts is suchthat the strop when in contact with the blade, moves downwardly againstthe opposite sides thereof.

In the drawings Figure 1 shows a side elevation of the invention with arazor, Fig. 2 represents a top view of the invention, Fig. 3 shows afront elevation of a blade carriage, Fig. 4 is a partialright hand sideView of Fig. 1 with a cross sectional view of the razor blade, Fig. 5represents a partial section as on the line 5, 5 of Fig. 1, Fig.

6 shows a section of Fig. 4 on line 6, 6, Fig. 7 shows a section of theblade carriage as on the line 7, 7, of Fig. 5 with a portion of asupplemental blade holder and its blade, Fig. 8 is a section of Fig. 7on the line 8, 8, Fig. 9 is a partial top plan view of Fig. 7, Fig. 10is a front View of a supplemental blade holder and Fig. 11 is anenlarged end view of Fig. 10.

The invention is shown to consist of a frame or holder with the sides 15having the main central openings 16, the guide openings 17, and theupper legs 18 at right angles thereto. An upper connecting plate 19joins the said legs 18, and a hook 20 for the handle 21 extends fromsaid plate 19. Upper tie rods 23, central tie rods 24 and lower tie rods25 connect the sides 15 of the frame. Guide rollers 26 and flangerollers 27, guide rollers 28 and flange rollers 29, are respectivelyjournaled on the upper tie rods 23 and the lower tie rods 25, while onthe central tie rods 24 are journaled the guide rollers 30.

The blade carriage of the invention comprises the cross-head 36 the endsof which project through and are guided in the openings 17 of the sides15. A housing 37 with the spring jaws 38 at the lower end thereof issecured to and extends below the crosshead 36. The jaws are connected atone end by a stop 39 and secure the blade 40 of a razor. A pair of posts41 extend up from the cross-head 36, and at the upper ends of said postsare fastened the ends of a spring 42, the central portion of whichlatter has a threaded opening for the adjusting screw 43.

Between the cross-head 36 and the spring 42 is located a presser plate45, which latter has the circular notches 46, by virtue of which it isheld in proper position by the posts 41. The ends of the cross-head 36have threaded openings for the adjusting screws 47 with the knurledheads 48, and the lower ends of said screws are rotatably joined withthe adjusting bar 49, that extends through the housing 37.

Guide rods 55 extend between the legs of the sides 15 on which arecarried the adjusting rods 56, by virtue of their forked ends 57straddling the rods 55. On the adjusting rods 56 are journaled theadjusting rollers 58 and 59, and between each pair of accompanyingforked ends 57 of the rods 56 there is located a separating spring 60,

the ends of which latter are secured to said forked ends 57. The rods56, rollers 58, 59 and springs 60 constitute a strop adjuster.

A stropwith the legs 65, 66 and handles 67, is connected with theinvention. The strop is located between the upper face of the cross-head36 and the lower face of the presser plate 45. The legs of the stroprespectively bear on the outer faces of the guide rollers 26 andadjusting rollers 58, 59 and also bear on the inner faces of the guiderollers 30 and 2 8.

In Figs. 7, 8, l0 and 11, a supplemental blade holder 70 is shownlocated and supported in the housing 37 of the blade carriage. Thesupplemental blade holder comprises the member 71,with the crown 72, andthe member 73 with the crown 74, the crown 74 hearing on the crown 72.The said members are joined by the rivet pin 75. The member 73 has theflange 76 which abuts against the lower edge of the member 71 to lockthe members together. In the member 73 is formed a recess 77, so thatthe members can be swung apart on the pin 75. In the member 73 areformed openings 80, and in the member 71 are formed openings 81 with theprojecting sleeves 82. The openings 80 of the member 73 are somewhatlarger than the outside diameters of the projecting sleeves 82 of themember 71; A safety razor blade 85 with the openings 86 is locatedbetween the members 71 and 73, the projecting sleeves 82 engaging theopenings 86 of the said blade 85.

To use the invention with an ordinary razor blade, the holder issuspended by means of the handle 21 and the razor blade 40 is insertedbetween the jaws 38 of the housing 37, the adjusting bar 49 beinglowered to bear against the back or crown of the blade, by turning theadjusting screws 47. The operator then alternately pulls the handles 67of the legs and 66 of the strop through the opening between thecross-head 36 and the presser path 45, by virtue of which the bladecarriage with the housing 37 will be moved to the opposite sides of theframe or holder, so that each side and edge of the razor blade 40 willbe brought to bear against the strop as the latter is being pulled bythe operator. The function of'the strop adjuster is to clear the razorblade 40, from the leg of the strop to which it is adjacent, before therazor blade with its carriage recedes therefrom.

When the blade carriage with its blades is adjacent to one of the legs66 of the strop as is plainly shown in Fig. 5, the first'effect ofpulling the other leg 65 of the strop is to clear the razor blade 40from the leg 66, by virtue of the action of the strop adjuster. The leg65 in such a case will bear against the roller 58 adjacent thereto, andmoves it on the guide rods 55 toward the other roller 59,compressing thesprings 60 by reason of w'h'i'chthe roller 59 will bear against the leg66 of the strop and push it away and clear of the razor blade, beforethe blade carriage begins to move away from said leg 66.

In case a special blade like 85 is to be stropped, it is secured betweenthe members 71 and 73 of the supplemental blade holder, the projectingsleeves 82 engaging the openings 86 of the blade 85 and extending intothe openings 80 of the member 7 3, the crown 74 bearing on the crown 72,and the flange 76 engaging the lower edge of the member 71. Thesupplemental blade holder with its blade is then inserted between thejaws 38 of the blade carriage, as already described when a regular razorblade is to be operated upon. Ifeither the regular style razor blade orthe supplemental blade holder is to be detached from the blade carriage,the adj usting screws 47 are turned, to disengage the adjusting bar 49from the crown of the razor or top of the supplemental blade holder.
